I have an air pump with twin outlets combined into one, feeding an airstone in the pond. Is there any advantage in putting a stone in my box filter? Some people think air in the bio filter is the greatest development in fish keeping in a long time. http://www.koivillage.com/filtration/nexus.html Download the PDF and dream a while. I can't afford one, but if I win the lottery, or in my next life maybe I'll set up a pond with one of these. Actually a friend is trying filter media in a barrel with an adequate air pump to agitate the media to see if we can do something similar. Regards, Hal I have twin outlets on my pump (with bio pre-filter), one going to the external filter and then the waterfall, and the other to a venturi pulling air from the surface and pushing water and air around the pond. Cheap and efficient. -- To reply by email, remove the word "space" |
